[Bug 880766] Re: Ubiquity fails with EFI and software RAID

[Andrew Cranwell]

I tried chrooting into the system and running grub-install then grub-
probe from there; the final lines were

/usr/sbin/grub-probe: info: opening md0,1.
/usr/sbin/grub-probe: error: no such disk.

Then I build grub from source (bzr revision 3473 from lp:grub) and ran
grub-probe, this time getting

/usr/sbin/grub-probe: info: opening mduuid/77de814b368e97ab4029c9d92332ed91,1.
ext2

So it looks like something has been fixed in grub that hasn't been
packaged yet.

Title:
  Ubiquity fails with EFI and software RAID

Status in GRand Unified Bootloader:
  New
Status in “grub-installer” package in Ubuntu:
  New

Bug description:
  Installing from a Mythbuntu amd64 CD booted in UEFI mode. Manually
  created partitions using gdisk, created RAID1 using mdadm. Ran
  Ubiquity installer to create /dev/md0p1 as ext4, install proceeded
  until aborting at the end saying that grub-efi could not be installed.

  Manual attempts to install grub also failed (both from the CD and
  chroot), so the problem package may actually be grub2.
